Keep the asynchronous integration workloads meaningful on slower OpenBSD
builders: preserve the original 50-message two-way workload after an upstream
refactor changed its counter from total messages to messages per peer, use one
producer per peer so that case measures bidirectional delivery rather than
redundant same-connection database contention, and give every asynchronous ACK
a distinct correlation ID.  Allow individual stress-test events more time,
poll queue state instead of sleeping for a fixed interval, and verify that all
network waiters resume without using host scheduler timings as a benchmark.
Run the upstream six-subscription batching scenario, which still crosses
multiple three-item batches, instead of the 200-connection stress variant that
exceeded even the five-minute port watchdog.  Give the 100-message
delivery-receipt workload a realistic platform-specific bound, and drive
client-notice checks from their reported expiration deadline instead of
sleeping exactly on a whole-second boundary.  Bracket the network-state agents
so their SQLite handles and worker threads cannot leak into later examples.

Also export and use the common timeout assertion for intentional
wrong-certificate connections.  A TLS cleanup regression must fail the test
instead of hanging the complete port build.
